Patent GB-1318366-A (GB)
Title: Valve device
IPC: F16K31/363
Filed: 1970-09-07
Abstract: 1318366 Valves VEREINIGTE FLUGTECHNISCHE WERKE-FOKKER GmbH 7 Sept 1970 [17 Sept 1969] 42806/70 Heading F2V In a 3-way pilot-operated valve, flow from inlet A to outlet B is controlled by valve member 23 connected to piston 21, and flow from inlet A to outlet C is controlled by valve member 31 connected to piston 27 by rod 44. With pilot valve 50 positioned as shown by its control magnets 57, 58, chambers g, 42 are vented at 56, 55 allowing spring 30 to expand such that valve member 31 assumes its closed position against stop 33 whilst valve member 23 assumes its open position with stop 26 abutting piston 27. During flow from A to B, valve member 23 will move against spring 30 to maintain a constant flow rate. By retracting the operating link 100 of magnet 58, pilot valve 50 shifts rightwards to connect chamber g to inlet pressure via 25, 17, 37, 35, and this results in an initial leftward movement of piston 21, until valve member 23 engages seat 15, and a subsequent rightward movement of piston 27 to move valve member 31 to its open position. By retracting both the operating links 100, 101 of magnets 57, 58, pilot valve 50 shifts further rightwards so that chambers g, 42 are both pressurized, allowing spring 30 to expand to maintain both valve members in their closed positions. In a modification, chamber 42 and piston 45 are omitted and a 3- way pilot valve selectively pressurizes or exhausts chamber g. In this case both valve members cannot be maintained in their closed positions together.

As described the mast 5 of a mobile rotary blast hole drilling machine is provided with three drill pipe racks 15, 16, 17 each movable between a storage position (shown in full line in Fig. 2) and a position over a drill hole (shown dotted Fig. 2). Each rack is secured to the mast 5 by parallel links 21, 25 (Fig. 3) and is moved between its two positions by hydraulic ram 29. Each rack can be locked in its storage position by a latch 32 operated by pneumatic ram 37, the control mechanisms for rams 29, 37 being interlocked so that latch 32 is always released before the rack moves out of its storage position. The bottom end of drill pipe 13 is screwed into socket 19 and the top end of pipe 13 is retained by a pair of jaws 63, 64 mounted on a common pivot 69. The jaws 63, 64 are biassed to their open position by springs 72, 73 (Fig. 5) acting on rearward extensions 70, 71 of the jaws 63, 64, and, when open, the inner ends 66, 68 of the jaws project into the space defined by the jaws (shown dotted Fig. 5) so that when a drill pipe is moved into the jaws they automatically close about the pipe. The jaws 63, 64 are locked in their closed positions by a locking wedge 81 (Fig. 6) which is urged between extensions 70, 71 by a compression spring 84. The wedge 81 is lowered to open the jaws by an air motor 62 acting through piston rod 85 and slide 82. The motor 62 is controlled by a valve (not shown) operated by a sensor 50 (Fig. 3) mounted on the socket 19 so that the jaws are automatically opened or closed as a pipe 13 is screwed out of or into the socket 19.

Abstract: 1337777 Valves ASW APPABATENFABRIEK NV 20 Sept 1971 [23 Sept 1970] 43758/71 Heading F2V A gas flow-controlling valve, which is designed for use in association with a water heater, not shown, comprises a closure member 4 which is located in the gas flow path 5, 2, and which, by way of a stem 6, is connected to a diaphragm 7, the diaphragm being subjected to the bias of a first spring 9. Extending into the stem 6 is a second stem 10 which is subjected to the bias of a spring 12 and which, by way of a washer 11, engages and acts upon stem 6 in a direction tending to seat valve member 4, the lower end of the second stem 10 being connected to a water guard, not shown. A throttled by-pass duct 18, 19 extends between the two chambers on either side of the diaphragm 7. In use, water flow in connection 3 raises the water guard and so allows the stem 10 to move against its spring bias 12 and hence, also allows stem 6 to move in a direction to unseat closure member 4. Such upward movement is checked by the passage of gas into the lower chamber 8 via the throttled passage 18, 19. In a modification, Fig. 2, not shown, the throttled passage is formed in the first stem 6. In both embodiments there is provided an electromagnetic safety device 14, 15, 16, 17 responsive to a pilot burner 13.

Abstract: 1,274,577. Cooling I.C. engines. DR-ING. h.c.F. PORSCHE K.G. 17 Sept., 1970 [20 Sept., 1969], No. 44490/70. Heading F4U. [Also in Division F1] A cooling system for vehicles provided with a primary internal combustion engine 5 for the main drive and a secondary internal combustion engine 10 for driving auxiliary equipment, comprises a cooling circuit 1 for the primary I.C. engine and a cooling circuit 2 for the secondary I.C. engine, both of said circuits being connected to a common cooling radiator 6. The cooling circuit 2 of the secondary I.C. engine 10, together with gearing 11 has a supply line 12 which is connected to the supply line 3 of the cooling circuit 1 and a return line 13 which is connected to the return line 4 of the circuit 1. A transmitter 21 is positioned in the return line 13, which via an electric conductor 22, is used for controlling an electromagnetic control valve 23 of an hydraulic installation 24. In operation, if the I.C. engine 5 is heavily loaded so that the effect of circuit 1 is no longer adequate, electrically driven supply pumps 16, 17, 18 of the circuit 2 are operated by switching on the ignition switch of the I.C. engine 10. If however, in spite of the switching in of the cooling circuit 2, the cooling effect is still not adequate, the I.C. engine 10 is brought into operation so that the gearing 11 drives the supply pumps 28, 29 of the hydraulic circuit 24. The pump 29 draws the hydraulic fluid from the oil supply container 32 via the pressure line 34 to the valve 23 which is connected by the transmitter 21 to a ventilator motor 36 so that the hydraulic fluid reaches the motor 36 through the line 35. As a result the motor 36 is driven and the radiator 6 and with it the cooling fluid of the circuits 1 and 2 are additionally cooled by the fan 37.

Abstract: 1,096,081. Stencilling apparatus. POSTER PRODUCTS Inc. Oct. 25, 1965, No. 45010/65. Heading B6C. Apparatus for printing on a sheet of porous material comprises (1) a stencil-carrying frame 22 reciprocated horizontally by the engagement of racks thereon with gears 9 fixed to an oscillated shaft 7, (2) a perforated panel 16 fixed to the shaft 7 and contacting the screen during an operation stroke of the apparatus and (3) a vacuum housing 45, Fig. 6 (not shown), beneath the panel 16 at the position where the panel contacts the screen, the vacuum causing colour composition 36, e.g. heavy non-flowing printing ink applied to the pervious parts 35 of the screen 33 to be deposited on the sheet. The sheet to be printed is fed over a table 63 and its leading edge is secured to the panel 16 by a clamp 60. The shaft 7 is now rotated anticlockwise so as to move the frame 22 to the left to perform an operation stroke. A pick-off mechanism 64 may be employed to deliver the printed sheet. The screen 33 is mounted in a frame 28 hinged at 37 to the carrying-frame 22, and is held in contact with the panel 16 during the printing stroke by the engagement of a nut 43 on a downwardly spring-urged plunger 40 mounted on the frame 22 with a tongue 41 on the frame 28. At the end of the operative stroke, the plunger 40 is raised by energizing a solenoid 39 and a second nut 43 on the plunger raises the frame 28 to an inoperative position so that when the shaft 7 is rotated clockwise as by means of a motor-reversing switch 76, Fig. 3 (not shown), the screen 33 and panel 16 are out of contact during their movement back to their initial positions. The suction housing is connected by a tube 57 to a vacuum tank 58 and is passed against the panel 16 by springs 55, Fig. 4 (not shown). If desired, the colour composition applied may be confined to a particular area of the screen by a boundary wall of rubber or metal. Prior to a sheet being fed through the apparatus, a partial solvent for the non-flowing printing ink employed is applied to its surface by a brush, sponge or spray. By applying differently coloured materials to different parts of the screen, multi-coloured printing may be effected.
